Survey: LinkedIn proves popular among business execs

Nearly 9 in 10 executives say they use LinkedIn "often" or "very often," according to a survey by DHR International. About the same percentage said they would use social media more if it helped their business more. "On average they spend between 30 minutes and an hour per week on social media, with a quarter saying they use it for between one to two hours and one in five using it more than two hours a week," Erik Sass writes.
